Abstract: Provided are elastomeric expansion joints for coupling tubes and, particularly, elastomeric expansion joint used for absorbing axial, lateral, angular movements and vibrations to which the tubes are subjected, or when these tubes are coupled to pieces of equipment that operate under varied conditions of temperature and pressure and that result in movement of the tubing. The elastomeric expansion joint is provided with wiring support members, which support wirings and that reinforce the elastomeric expansion joint, so that the elastomeric expansion joint can stand higher pressures. A method of manufacturing the elastomeric expansion joint is also provided.
